FOLDING PERAMBULATOR.

Application filed December 5, 1904.

To all whom t may concern.'

,le it known that I, ALBERT E. MCGILL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Folding Perambulaters,of which the following is a full, clear, and exact specification.

My invention relates more particularly to that type of foldingperambulators or gocarts especially adapted for the use of children andprovided with means whereby the seat and handle as well as the wheelsmay be folded into a substantially fiat, compact form, and the inventionhas for one of its important objects to provide a folding, recliningback for the seat of a device of this character which shall be capableof being adjusted to various positions and folded into a compact formwith the balance of the device when not in use.

`With a view to the attainment of these ends and certain other objectswhich will hereinafter appear, the invent-ion consists in the featuresof novelty hereinafter described with reference to the accompanyingdrawings and more particularly pointed out in the claims.

In the said drawings-Figure 1 is a side elevation of my improvedperambulator. Fig. 2 is a plan view thereof. Fig. 3 is a verticalsectional View showing the back of the seat in different positions indotted lines. Fig. 4 is an enlarged detail view of one of the supportsfor the back. Fig. 5 is an enlarged plan view of the chain clutch. Fig.6 is a sectional View thereof on the line 6, 6 Fig. 5. Fig. 7 is anenlarged detail viewof the catch for securing the sections of the backtogether. Fig. 8 is a front elevation of the complete device. Fig. 9 isa vertical, longitudinal, sectional vView of one of the side bars of theseat frame on an enlarged scale. Fig. 10 is a vertical, longitudinalsection of one of the side bars of the running gear frame taken throughone of the forks and showing the means of locking the fork in position.Fig. 11 is a perspective View of the upper end of another one of theforks and the tube support, and Figs. 1Q to 15 inclusive illustrate acertain Specification of Letters Patent.

modification hereinafter described, Fig. 1Q- being a vertical sectionalview of part of the device taken on the line 1Q, 12 Fig. 13, F ig.'13 isa section on the line 13, 13 Fig. 12, Fig. 14 is a section similar toFig. 12 showing the parts folded up, and Fig. 15 is a detail perspectiveview of one of the guide lugs on the lower end of the back.

The rear wheels 1 are mounted in forks or supports Q which have collars3 at their upper ends rigidly secured to the rear ends of two sleeves ortubes 4 which are journaled upon the side bars 5 of the running gearframe, the forward ends of these side bars being connected together by across bar G preferably formed integrally therewith The front wheels 7are journaled in suitable forks or supports 8 which have collars 9 alsorigidly secured to the tubes or sleeves 4 at their forward extremitiesand these collars 9 are formed with shoulders 10 which are adapted toengage shoulders 11 formed on collars 12 rigidly secured to the sidebars 5, thus limiting the rotative movement of the sleeves 4 and theforks 2, 8 while allowing the forks and wheels to be folded togetherunder the running gear frame, the front forks being thus rigidlyconnected to therear forks in pairs by the tubes 4, however, will movein unison with the rear forksl when they are turned and will be held inposition when the rear forks are locked. In order that the rear forksmay be thus locked locking pins 13 are provided for each of the collars3 and the side bars 5, as sho-wn in detail in Fig. 10, and these bars 5are connected together across the running gear frame by a cross bar 14which is pivoted at its ends to the lower links 15 of two toggles whoseupper links 16 are pivoted to collars 17 on handle 18, the latter beinghinged at 19 to lugs 2() on the rear ends of side bars 5. The downwardmovement of toggle center 21 islimited by any suitable stop 22 so thattoggle levers will be held in a straight line4 while the handle 18 islowered to a position substantiallyv parallel with the running gearframe, the center 21 being in the meanwhile carried forwardly withreference to the cro-ss bar 14. The cross bar 14 is also connected bydeflectable standards or braces 23 to the upper or rear ends of two sidebars 24 of the seat frame, by means of suitable clips 25 and these sidebars 24 are hinged at their forward ends to the side bars 5 of therunning gear frame, so that when vthe handle is folded downwardly andforwardly the seat frame will be also lowered into its folded positionand when the handle is raised the seatr frame will be raised to theposition shown in Fig. 1 by virtue of its connection to the handle.`

The forward ends of the bars 24 are pivoted on the upper horizontal.portions 26 of U-shaped supports which have downwardly extending` stems27 secured in the side bars 5, the bends of this U being turned inwardlyso as to support the seat frame at a position wholly within the runninggear frame as better shown in F ig. 2 and also within the handle 18which is as wide as the running gear frame and wider than the seat frameand consequently will, when folded, occupy a position substantially inthe same plane as the seat frame whose forward end terminates a littleshort of the forward extremity of the running gear frame and of thehandle when-the latter is folded down upon the running gear frame. Thestandards or braces 23 together with the cross bar 14 constitute aU-shaped or tri-lateral frame supported upon the rear end of the runninggear frame at its lower end and pivotally supporting by its upper endthe upper end of the seat frame and also carrying at its lower end thedownwardly proj ecting taperpins 13 which pass through the tubularmembers of the running gear frame and wheel supports and lock themtogether. Thus it will be seen that the cross bar 14 of this U-shapedframe serves not only the im- 'portant function of holding the lowerends of the braces or standards 23 from spreading or deliectinglaterally with relation to the running gear frame, but the furtherimportant function of rigidly tying together and bracing the rearmembers 5 of such running gear frame which might otherwise spread whilethe cart is in use. In addition to this it also makes it possible toconstruct the braces or standards Q3 of comparatively light stock orbars while affording ample stock at the lower ends for the attachment ofthe t-aper-pins 13, the outer extremities of the bar 14 being olfsuiiicient body to provide for the firm attachment-of the standards 23as well as the taper-pins 13 and the links 15, which latter might causethe taperpins to rotate in their sockets and twist the standards orbraces 23 were it not for the continuous connection from side to sideafforded by the bar 14.

To the side bars 24 of the seat frame are secured the rods 28 whichsupport the upper ends of the side portions 29 of the seat and in orderthat these side portions 29 may not slide down the rods 28 the latterare formed with offsets or notches 30, see Fig. 9, into which thematerial of the side portions 29 are depressed by pins 31 whichconstitute the pivots for the upper ends of standards 23.

rllhe upper end of the seat frame is provided with an extensioncomprising two stems 32 and a cross bar 33 which is preferably formedintegrally with these stems and the stems are inserted. in the side bars24 respectively so that when desired the seat 'frame may be extended adistance equal to substantially the full length of these stems 32, theupward movement of the stems being checked if desired by any suitablecatches in the form of rings 33l slipped over the upper ends of the sidebars 24 and adapted to drop through slots 35 in each of said side barsand engage in a notch 3G in eachof the stems when the stem has beenpulled outwardly a suflicient distance to bring the notch 3G intoregister with the slot To this extension of the seat frame is attached'the upper end of an adjustable, extensible back which will now bedescribed. This back consists preferably of three sections, 37, 38, 39which are connected together bysuitable hinges 40, 41'1 and the twosections 37, 38 are 'd of such length that when the extension of theseat frame is at the lower extremity of its movement they willsubstantially fill the space between the upper end of said extension andthe bottom 41 of the seat to which the .section 37 is hinged at 42 byany suitable means, and when in this position the back is supported fromthe cross barr33 of the seat frame extension. The means for thussupporting the back preferably consists of two brackets better shown inFig. 4 and coniprising horizontal portions 43 projectingA toward eachother between the sections i 38, 3S) of the back, and Verticalportions-44 are passed through the cross bar 33 and are thence returnedinto the cross bar as shown at 45 and held by any suitable means as alnut 46.' The end of the back section 39 which is lower-most when theback is in the position shown in Fig. 3, is attached to a chain or othersuitable iiexible connection 47 which is passed upwardly through aclutch of any appropriate form such as a key hole slot 48 formed in thelugs 49 on the rear side of cross bar 33 and adapted to grip the chainat any position of its adjustment. It will thus be seen that when theseat frame extension is pulled upwardly in the position shown in dotted`lines inFig. 3, the back sections may be unfolded as also shown in saidligure and thereby produce a reclining hack. The degree of inclinationof the back may then be varied to suit the requirements by merelymanipulating the chain in the clutch 4S, allowing it to run downwardlythrough the larger part of the key hole slot until the desiredinclination is reached when it may be fastened by simply slipping one ofthe links into the narrow portion of the slot.

When the back is to be folded up with the seat and the running gearframe, the lower end of the section 3S), which is ordinarily held inplace by any suitable clip comprising two members, one of which isattached to section 37 and the other to section 39, is raised from theposition shown in Fig. 3 and turned forward until the hinge 40 arrivesat the bottom 4l and the section 39 is straight with the section 3S, thepurp ose of the short section 38 being to compensate for the differencein the distance between the hinge 40 when it is thus lowered and thesupporting brackets 43 and said brackets 43 and the hinge 42 when theback is in the position shown in Fig.` 3. The seat frame will now belowered, carrying the upper end of the section 39 downwardly with it onan arc taking the hinge 40 as a center, thus bringing the folded backflat upon the bottom of theseatand the seat of course is lowered betweenthe side bars of the running gear frame as the seat frame descends.

Referring now to the modified form illustrated in Figs. l2 to 15inclusive, it will be seen that instead of hinging the lower edge of theback member or section 37 to the bottom 41 at a tixed point, it isprovided with a-sliding hinge capable of allowing the lower edge of saidback section to slide forwardly when the seat frame is folded up, andthus do away with the additional section 38 employed in the other form.rllhis sliding hinge may be constituted by a pair of keepers 51 securedto the bottom 4l and a pair of pivots or lugs 52 secured to the loweredge of the back section 37 and projecting outwardly into engagementwith the keepers 51. `When the back is in use these lugs 52 are at therear ends of the keepers, as shown in Figs. 12 and 13, but when it isfolded up they slide forwardly in the slots constituted by the keepersand the surface of the bottom part of the seat as shown in Fig. 14 thusallowing the upper part of the back to descend with the brackets 43 andseat frame, which latter partially embraces the back section as shown inFig. 14.
